Introduction. Construction of large-span and super high-rise concrete structures has become a current trend [], posing an increasingly stringent requirement for the compressive strength of concrete.For this reason, self-compacting concrete (SCC) with high strength, self-compacting ability, and excellent load-bearing performance has been gradually used in civil engineering.

Apr 11,  · The optimization of mixture design factors based on the mathematical models was carried out to select the appropriate factors combinations; a good agreement between the experimental results and the predicted results was obtained. Hadji, T., Guettala, S. and Quéneudec, M. ( ), "Mix design of high performance concrete with different

Laboratory and in situ test results reveal that the densified mixture design algorithm (DMDA) can be used to produce high-performance concrete (HPC) of good durability and high workability. The water-to-solid (W/S) weight ratio is known to have significant influence on the volume stability of concrete.

High-performance concrete is produced by careful selection of raw materials such chemical admixtures and appropriate mix design to achieve the desired performance objectives. High-strength concrete is achieved at low water to cement ratio which is obtained by adding water reducing plasticizer or high range water reducing plasticizer.

Abstract An optimization experimental program was designed to identify a desired balance of key mix design parameters for an economical ultra-high-performance concrete (UHPC) mixture. The following mix design parameters were evaluated: superplasticizer content, coarse-to-fine aggregate ratio and steel fiber volume fraction. The values of packing density, water film thickness and excess paste

The total cost of the concrete structure is the sum of the costs of its constituent materials; these constituent materials are at least: concrete, reinforcement steel and formwork, (Sarma and Adeli, 1998) [2], [3]. There are some characteristics of reinforced concrete (RC) structures which make their design optimization distinctly different from

Metal forms were used to cast concrete blocks approximately 3 feet by 4 feet by 4 inches thick, utilizing Euclid Chemical concrete admixtures and macro synthetic fibers. The concrete blocks were tied together with a stainless steel wire, picked up by a crane and loaded

As abundant CO 2 is released by high-strength concrete due to its high binder content, the reduction of CO 2 emissions has become increasingly important. This study proposed a general procedure to optimize the mixture design of low-CO 2 high-strength concrete containing silica fume. First, the equations for evaluating strength and slump were regressed based on available experimental results.

Concrete Mix Design Introduction The process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design. The proportioning of ingredient of concrete is governed by the required performance of concrete []

Modern Concrete Science ”. Based on these theories, computer models and software can be developed for theoretical prediction of concrete performance. It is envisaged that such computer software can finally help to optimize our mix design for better HPC and allow quicker response during production to variations in quality of the ingredients.

A concrete mix design method is used taking into account granulation parameters of aggregates. The task of concrete mix optimization implies selecting the most suitable concrete aggregates from the Data Base. The following properties are to be optimized: cost of raw materials, quality of aggregate packing, water and cement consumption.
